System with reloadable handle for delivering an anchor
View Patent ↗An anchor delivery system configured for single patient, multiple use applications. The system includes reloading linkages which cooperate with needle, suture and anchor subassemblies and devices. Reloading actions accomplish the acceptance of a subsequent anchor cartridge and the readying of delivery structure.
1. A system for deploying an anchor assembly, comprising:
a replaceable cartridge carrying the anchor assembly; and
a handle configured to couple with the replaceable cartridge, wherein the handle includes a reloading linkage cooperating with the cartridge, a needle assembly, a needle release and retraction trigger, a reloading lever, and a proximal anchor delivery structure and wherein the cartridge includes three slide tabs which engage three spring device sleds.
2. The system of claim 1 , wherein the handle includes a first reloading linkage cooperating with the needle assembly and a second reloading linkage cooperating with the proximal anchor delivery structure.
3. The system of claim 1 , wherein the reloading lever is attached to the reloading linkage.
4. The system of claim 1 , wherein the reloading linkage includes a first elongate point and a second elongate point formed at an angle with the first elongate point.
5. The system of claim 4 , wherein the first elongate point includes a slot extending substantially an entire length of the first elongate point.
6. The system of claim 5 , wherein the slot is sized and shaped to receive a member extending from one or more of a proximal anchor sled and a needle sled.
7. The system of claim 1 , wherein reloading of the system involves compression and latching of a needle spring and a proximal anchor spring.
8. The system of claim 1 , further comprising a suture spring and a needle spring, wherein the suture spring is compressed upon release of the needle spring.
9. The system of claim 1 , further comprising a needle spring and a suture spring, the needle spring and suture spring being arranged laterally side by side.
10. The system of claim 9 , further comprising a proximal anchor spring arranged above the needle and suture springs.
11. The system of claim 1 , further comprising a suture sled, wherein the suture sled is held in a closed distal position during a first few centimeters of needle assembly retention.
12. The system of claim 1 , wherein the proximal anchor is held in a reloaded position until after retraction of the needle assembly.
